To all whom t may concern:`

Be it known that I, FELIX Gr. KAPELMAN, a citizen of the United States, residing in New York city, in the county of Bronx and State of New York, have invented certain new and useful Improvements in Corner- Locks for Metal Frames, of which the folu lowing is a specification.

This invention relates in general to means for locking two sections together at an angle to one another.

One of the main objects of the presentinvention is to provide a corner lock for locking two sections of angle irons together at an angle to one anotherV which corner lock is mainly composed of standard sheetiron angular pieces. j j Y j The present corner lock finds adaptation with bed frames asillustrated. l

These and other'features, capabilities and advantages of the invention will appear fromthe subjoined detail description of one specific embodiment thereof` illustrated in the accompanying drawings, in which- Figure 1 is a ragmentalplan view showl ing the corner lock secured to a bed post. Fig. 2 is a fragmental `elevational view` of the same. j i

Fig. 3 is a section along the line 3-3 of Fig. 2.1

Fig. 4 is a fragmentalpejrspective of one of the parts of the lock; and Fig. 5 is a fragmental perspective of another ofthe parts of the lock. i

Fig. 6v is a fragmental plan view of the part illustrated in Fig. 4; and Fig. `7 is a fragmental plan view of the part illustrated inFig. 5.

In the embodiment illustrated there is shown a bed-post `and a bracket B secured to such post by a vertical pin in the usual manner. The bracket in the present instance is riveted by means of two rivets 8, 8, to the arm 9 of one of the main parts 10 of the corner lock.

11 and 12 indicate, generally, the sections to be secured to one another, member 11 in this case, as shown in the drawing, being one side-rail of the bedstead. The part 10 of the lock, which is a bracket in Jform, comprises essentially a web portion 13, the arm 9 extending from one side thereof and the arm 14 extending from the other side thereof. rlhe upper end of the web portion 13 is referablyv recessed at 15, as shown, and near its lower edge is secured the rivet 16 which Specification of Letters Patent. Pghtmtdl iDEQ., jljll, 191W, animation inea December 29, 191e. serial No. 139,450.

has a head 17 p (Fig. 7) spaced from the rear face of the web portion 13 a distance substantially equal to a thickness of the sheet metal pieces being used.

To theinner upper side of the arm 14 is rigidly secured one end of the section 11 l which is of angle iron construction'in the present instance and has its horizontally Aextending portion 18 cut away adjacent to the arm 14, as shown at 19, to facilitatethe operationV of the screw 2() about to be described. j v j i p p j The screw 20 has a lower screw threaded end 21 coperating with the laterally extendingarm 22 of the bracket 23 pivotally connected to the inner sidel` offtheiarm-14 belowthe section 11. The upper end of `the screw 2,0 is provided with a wing 24 for manipulating the same, havingaflat face 25` below such wing 24 for cooperating with the horizontally extending arm 26 of thesestion 12.` j 'j j The arm` 26`is provided at one end with an voutwardly flaring recess 27 to receive the shank of the screw 20. Below the recess 27 there is provided a plate `28 which is riveted tothe vertically extending arm 29 of the section 12. The upperend of ythe plate 28 adjacent to the arm 26, has an4 elongated downwardly projecting inger'BO, and the lower end of the .plate 28 isV providedwith arecess 31. f j

In the assembling of the corner lock, the web portion 13 of thepart 10 is placed against theplate 28 with its arms 9 and 14 extending inthe direction of the arm 26, with its recessed portion 15, thrust under the finger 30 and the rivet 16 thrust.` into the recess 31. Thereupon the screw 20, which shall have been tilted to one side, Vwill be rocked over so that its shank enters the recess 27, and its head 24 is disposed above the arm 26 and then the screw 20 is screwed down with its face 25 drawn tightly against the arm 26.

It is obvious that various changes and modifications may be made to the details of construction without departing from the general spirit of the invention.

I claim:

1. Ihe combination with two sections, of a corner lock for connecting said sections to one another at an angle, said lock comprising a plate member secured at substantially a right angle to one of said sections, a second plate member secured to the other of said sections' parallel therewith, saidv plate members being adapted to be interlocked with one another,` a screwpvotally connected to said lirst plate member, a horizontally extending arm on the section to mg said screw, and a head on said screw for engaging said arm lwhen said" screw is lQQlQft inte Said recess S0. that When the Screw is. drawn tight it Will Securely anchor thefiyletes t0 011e another in intrhwked4 P0- stion. y p' l 2. 'I he c ombination'with two sections, of a corner lockA for connecting said sections to one another at an angle, said'r lock comprising `ai plateA member Secured to eachl section, arjivetonthe lower end of one of said plate mennbers,Y ax linger on. the upper end'oil the other plate member anda recess at its lower end, the linger receiving 'the upper edge of theiirst namedL platemember and the recess receiving the rivet Vof said 'first named plate memberfand a screw pivoted to one ofthe plates fdr anchoring said plate members in iiterlocked, position.

I 3. rllhe combination with two"sections,gof a cornerlock for connecting saidy sections to one lanotlfier at an`- angle, saidj lock comprising ajplate member lsecuredto each section, thepl'a'te members being adapted to be interlockedwith one another, a bracket pivotally IlQlllldY onfone of said platemembe'rs, a screw screwthreadedly connected to said bracket, fand a head on said screw for engaging the sectionl Lto which .the other plate member is connected so that when the screw is. drawnl tightly the plate members will be securely anchored, to one another in inter- LOQked-i'pesitem 4. The combination with two sections, of a corner-lock comprising .an interlocking tongue and, groove carried by the sections forseparably 'connecting said sections together at substantially a, rigl 1tangle oneto the other; and; a vibrating locking-member. piyotedj to one sectiom the other adjacent right-anglednsection: beingy cut-away or cham- Gopieisfot this patent may; be obtained for live cents each, by addressing the fered to permit of free vibration of the locking-member.
